math.SmallestNonzeroFloat64 Constant

The SmallestNonzeroFloat64 constant is an inbuilt constant of the math package which is used to get the smallest positive, non-zero value of float64 type.

The value of math.SmallestNonzeroFloat64 constants is 4.9406564584124654417656879286822137236505980e-324 or 0x1p-1022 * 0x1p-52.

Syntax:

float64 math.SmallestNonzeroFloat64

Parameter(s):

• None

Return Value:

The return type of math.SmallestNonzeroFloat64 constant is float64, it returns the smallest positive, non-zero value of float64 type.

Example 1:

// Golang program to demonstrate the
// example of math.SmallestNonzeroFloat64 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.SmallestNonzeroFloat64 is %T\n", math.SmallestNonzeroFloat64)
	fmt.Println("Value of math.SmallestNonzeroFloat64:", math.SmallestNonzeroFloat64)
}

Output:

Type of math.SmallestNonzeroFloat64 is float64
Value of math.SmallestNonzeroFloat64: 5e-324

Explanation:

In the above program, we imported the math package to use the math.SmallestNonzeroFloat64 constant, then printed the type and value of the math.SmallestNonzeroFloat64 constant.

Example 2:

// Golang program to demonstrate the
// example of math.SmallestNonzeroFloat64 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of SmallestNonzeroFloat64.
func getSmallestNonzeroFloat64() float64 {
	return math.SmallestNonzeroFloat64
}

func main() {
	fmt.Println("Value of math.SmallestNonzeroFloat64:", getSmallestNonzeroFloat64())
}

Output:

Value of math.SmallestNonzeroFloat64: 5e-324
